Arndale board has AX88760, which is USB 2.0 Hub & USB 2.0 Ethernet Combo controller, connected to HSIC Phy of USB host controller via USB3503 hub.
This patch implements a board specific board_usb_init function in
ehci
driver to perform reset sequence for USB3503 hub and enables the relevant config options for network to work.

__attribute__((weak, alias("__exynos_board_usb_init")));Sorry, this is not happening. Why can you not use the existing board_usb_init() and instead have to invent new stuff ?
I did not use board_usb_init because it has 2 parameters which may not be used as described in usb.h for my use case, which is to only configure gpios for reset and connect of usb 3503 hub.
Let me know if you still feel that board_usb_init should be used. In that case I will have to utilize index parameter in my own way.
Shall I read that as "I will abuse API" ? You know that this will not happen ;-)
Yes, thats an abuse and have not done that yet :-)
Why can you not reset the USB HUB in regular board_usb_init() simply by toggling the switch's reset gpio as done on the rest of the boards ?
Ok, let me try this. If it works I will send the updated patch.
